Create an HTML table
You are encouraged to solve this task according to the task description, using any language you may know.
Create an HTML table.
- The table body should have at least three rows of three columns.
- Each of these three columns should be labelled "X", "Y", and "Z".
- An extra column should be added at either the extreme left or the extreme right of the table that has no heading, but is filled with sequential row numbers.
- The rows of the "X", "Y", and "Z" columns should be filled with random or sequential integers having 4 digits or less.
- The numbers should be aligned in the same fashion for all columns.
Ada
We define a generic package to output HTML tables:
<lang Ada>with Ada.Strings.Unbounded;
generic
type Item_Type is private; with function To_String(Item: Item_Type) return String is <>; with procedure Put(S: String) is <>; with procedure Put_Line(Line: String) is <>;
package HTML_Table is
subtype U_String is Ada.Strings.Unbounded.Unbounded_String;
function Convert(S: String) return U_String renames
Ada.Strings.Unbounded.To_Unbounded_String;
type Item_Array is array(Positive range <>, Positive range <>) of Item_Type; type Header_Array is array(Positive range <>) of U_String;
procedure Print(Items: Item_Array; Column_Heads: Header_Array);
end HTML_Table;</lang>
The implementation of the package:
<lang Ada>package body HTML_Table is
procedure Print(Items: Item_Array; Column_Heads: Header_Array) is
function Blanks(N: Natural) return String is
-- indention for better readable HTML
begin
if N=0 then
return "";
else
return " " & Blanks(N-1);
end if;
end Blanks;
procedure Print_Row(Row_Number: Positive) is
begin
Put(Blanks(4) & "" & Positive'Image(Row_Number) & "");
for I in Items'Range(2) loop
Put("" & To_String(Items(Row_Number, I)) & "");
end loop;
Put_Line(""); end Print_Row; procedure Print_Body is begin Put_Line(Blanks(2)&"<tbody align = ""right"">"); for I in Items'Range(1) loop Print_Row(I); end loop; Put_Line(Blanks(2)&"</tbody>"); end Print_Body; procedure Print_Header is function To_Str(U: U_String) return String renames Ada.Strings.Unbounded.To_String; begin Put_Line(Blanks(2) & "<thead align = ""right"">"); Put(Blanks(4) & "");
for I in Column_Heads'Range loop
Put("" & To_Str(Column_Heads(I)) & "");
end loop;
Put_Line(""); Put_Line(Blanks(2) & "</thead>"); end Print_Header; begin if Items'Length(2) /= Column_Heads'Length then raise Constraint_Error with "number of headers /= number of columns"; end if; Put_Line("
"); Print_Header; Print_Body; Put_Line("");
end Print;
end HTML_Table;</lang>
Here is the main program, using an instance of HTML_Table:
<lang Ada>with Ada.Text_IO, Ada.Numerics.Discrete_Random, HTML_Table;
procedure Test_HTML_Table is
-- define the Item_Type and the random generator type Four_Digits is mod 10_000; package Rand is new Ada.Numerics.Discrete_Random(Four_Digits); Gen: Rand.Generator;
-- now we instantiate the generic package HTML_Table
package T is new HTML_Table
(Item_Type => Four_Digits,
To_String => Four_Digits'Image,
Put => Ada.Text_IO.Put,
Put_Line => Ada.Text_IO.Put_Line);
-- define the object that will the values that the table contains The_Table: T.Item_Array(1 .. 4, 1..3);
begin
-- fill The_Table with random values
Rand.Reset(Gen);
for Rows in The_Table'Range(1) loop
for Cols in The_Table'Range(2) loop
The_Table(Rows, Cols) := Rand.Random(Gen);
end loop;
end loop;
-- output The_Table
T.Print(Items => The_Table,
Column_Heads => (T.Convert("X"), T.Convert("Y"), T.Convert("Z")));
end Test_HTML_Table;</lang>
Each time you run the program, you get different random values for the table.

Bracmat
To make this interesting, the table is created as a Bracmat structure and then converted to XML by a library. This has the advantage that one doesn't have to worry about HTML entities and encoding issues. The contents of the cells are generated by a function that is instantiated with a starting number when the function makeTable is called. Notice the absence of loops. <lang bracmat>( ( makeTable

- with any templating solution built for JavaScript, and of course you
- can build tables in the browser using DOM APIs. This approach is just
- brute force string manipulation.

Forth
Printing out a group of HTML text strings is not difficult for Forth or most computer languages.
Another way to do this in Forth is to extend Forth with new "words" that output the HTML tags.
The HTML words will output HTML code when they are interpreted by Forth. In this example the extended Forth code looks at lot like HTML. :-) The biggest difference is that Forth requires 1 space minimum between each tag.
Although this example is not a complete HTML interpreter, with these few extensions we can demonstrate mixing HTML tags with Forth code to generate the specified random numbers in-line with HTML. We could even use Forth to compile tags together and make HTML generating sub-routines like NETREXX does.
<lang Forth>include random.hsf

-1 >in +! \ move the interpreter pointer back 1 char
pad count type ;
- '"' [char] " emit ;
- '"..' '"' space ; \ output a quote char with trailing space
- toquote \ parse input to " then print as quoted text
'"' [char] " PARSE pad place
pad count type '"..' ;
- > [char] > emit space ; \ output the '>' with trailing space

Fortran
Origin
The task could be achieved by a series of direct WRITE statements, with some simple loop to generate N lines for the table. This would not show anything beyond the usage of WRITE statements, possibly obfuscated by cunning FORMAT sequences. Instead, what follows is a trimmed version of some routines that were used for writing HTML tables of various shapes, with perhaps dozens of columns and hundreds of rows. The idea was that module HTMLSTUFF would contain an attempt at organised assistance for the task. The system would produce output tables according to the type of the output file: space-aligned or, if .csv then comma-separated, or if .html then it used the HTML table protocol. In-line code was used for the details of the body of the tables because their cells involved different types and layout (and even decoration, as with RED ... DER for negative correlations) but here the task requires only HTML and that each row show only integers so it seemed worthwhile to devise a subroutine for writing a row of integers and likewise for a row of texts. Thus, the caller need not worry over the multitude of details involved in preparing a well-formed HTML file, just invoke some subroutines with a few parameters. This is done in the mainline. The specification is for columns headed "X", "Y", and "Z" but a proper table would have more useful annotations.
These routines were written to wallow in a much larger context.
For instance, each subprogram would start with a call to SUBIN naming the subprogram, and just before exit each would invoke SUBOUT.
A stack of active names was thereby maintained, and was available for use by subroutine ECART (to produce trace output, annotated via the name stack with the name of the routine requesting that output), and subroutine STATE that accepted a text declaring the activity about to be started (surprisingly useful when checking and documenting the source), and if there was a disaster, subroutine CROAK reported its message and what was being attempted at each level back to the start. Similarly, (almost) all output to the screen was echoed to file TRAIL and after every 6666 lines written to the screen, there was an opportunity to stop a runaway output, and details for the I/O unit variables and associated arrays were in named COMMON via file cIOunits.for. Most of this has been commented out.
There was also an attempt at dealing with annoying differences in glyphs between keyboard input, screen display, and the display rendered by text editors.
This had to be extended for HTML output as certain character codes also evoked an unsuitable glyph and others interfered with the interpretation of text versus instructions.
The first part of the source therefore is a wad of support routines, starting with a text I AM (see the painting by Colin McCahon) that names the programme, and another that is filled with the user's code identity.
These are used in the metadata for the HTML.
Since the HTML text that results was going to be inspected by eye to catch blunders there was a lot of attention to layout, in particular the use of indenting as each level was tracked by INDEEP, and the content of a row was to appear on one (possibly long) line. Browsers often pass over hiccoughs and still present a correct-looking display, thus it is useful to employ HTML-checking routines. I have considered adding various checks to the routines in HTMLSTUFF such as that when a level was closed, its interior levels had also been closed off, but that would mean even more cogitation. Avoiding endless text shuffling was another objective, thus rather than concatenate pieces and write the result, routine HTML3 has three parts, a preamble, a body, and a tail to generate a complete line. Further, for layout assistance, if the preamble was not empty then it would be written on a new line and indented according to INDEEP, and if the tail was not empty then it would be written and the line ended.
It is tempting to prepare a similar routine for presenting a single item, say HTML3TERM("<th>",TEXT(I)(1:L),"") rather than preparing a compound string via "<th>"//TEXT(I)(1:L)//"" first. Even more direct would be to use WRITE statements straight to the output file, employing suitable FORMAT statements, but in the larger context it was more useful to avoid this since with all output in one place via subroutine WRITE, mishaps could be attended to in one place only.

Concocted yet again by R.N.McLean (whom God preserve) December MM.

TEXT(L:L).LE.' ') !Control chars. regarded as spaces. Curse the morons who think it good that the compiler MIGHT evaluate logical expressions fully. Crude GO TO rather than a DO-loop, because compilers use a loop counter as well as updating the index variable. Comparison runs of GNASH showed a saving of ~3% in its mass-data reading through the avoidance of DO in LSTNB alone. Crappy code for character comparison of varying lengths is avoided by using ICHAR which is for single characters only. Checking the indexing of CHARACTER variables for bounds evoked astounding stupidities, such as calculating the length of TEXT(L:L) by subtracting L from L! Comparison runs of GNASH showed a saving of ~25-30% in its mass data scanning for this, involving all its two-dozen or so single-character comparisons, not just in LSTNB.

Copying all (hundreds!) is excessive; these seem possible for the usage so far made of error diversion. Compaq's compiler interface ("visual" blah) has a help offering, which can provide error code information. Compaq messages also appear in http://cens.ioc.ee/local/man/CompaqCompilers/cf/dfuum028.htm#tab_runtime_errors Combines IOSTAT codes (file open, read etc) with STAT codes (allocate/deallocate) as their numbers are distinct.

C Once upon a time, there was just confusion between ASCII and EBCDIC character codes and glyphs, c after many variant collections caused annoyance.

I would have preferred to fiddle the c "code page" for text output that determines what glyph to show for which code, but not only c is it unclear how to do this, even if facilities were available, I suspect that the screen display c software only loads the mysterious code page during startup. c This fiddling means that any write to MSG should be done last, and writes of text literals c should not include characters that will be fiddled, as text literals may be protected against change.

- generate the HTML from a functional expression which, for ease of legibility and refactoring, visually resembles the structure of the HTML table code itself.

return blnAlpha ? lstInt.map(
function (x) {

- NewLISP allows almost any character in an identifier, so I can name
- my functions after the HTML elements they invoke. This one formats a
- single table data cell.
(define ( text) (pad (string "" text "")))
- "" will accept either a number of arguments, each one to be
- formatted as a table cell, or a single list argument, which is
- broken into table cells. For convenience, I format each list item
- with the "" function so I can feed it raw lists.

- By defining "" as a macro, I ensure that the rows won't be
- evaluated until I've got the table started, which preserves the
- formatting.

print_endline (Buffer.contents buf)</lang>
With a dedicated library
Using the library ocaml-xhtml. With this library the validity of the pages is guaranteed by the OCaml type system.
<lang ocaml>open XHTML.M_01_01
let _td s = td [pcdata s] let _th s = th [pcdata s]
let my_table =
table ~a:[a_border 1]
(tr
(_th "") [
(_th "X");
(_th "Y");
(_th "Z")]
)
[
(tr
(_td "1") [
(_td "aa");
(_td "bb");
(_td "cc")]
);
(tr
(_td "2") [
(_td "dd");
(_td "ee");
(_td "ff")]
);
]
let my_page =
html
(head (title (pcdata "My Page")) [])
(body
[ h1 [pcdata "My Table"];
my_table;
]
)
let () =
pretty_print ~width:80 print_string my_page</lang>
TyXml
The library TyXml contains a module for XHTML that provides the same interface than the previous ocaml-xhtml library.
<lang ocaml>#use "topfind"
- require "tyxml"
module X = Xhtml.M_01_01 (* XHTML 1.1 *) module P = Xhtml.P_01_01
let make_table () =
let td1 = X.td [X.pcdata "1"] in let td2 = X.td [X.pcdata "2"] in let td3 = X.td [X.pcdata "3"] in let my_tr = X.tr td1 [td2; td3] in let my_table = X.table my_tr [] in (my_table)
let () =
let my_title = X.title (X.pcdata "My Page") in let my_head = X.head my_title [] in let my_h1 = X.h1 [X.pcdata "My Table"] in
let my_table = make_table () in
let my_body = X.body [my_h1; my_table] in let my_html = X.html my_head my_body in P.print print_endline my_html;
- </lang>
The previous function make_table () produces a simple table, we can replace it by the function below to output a more complex table with thead and tbody:
<lang ocaml>let make_table () =
let br = X.a_border 1 in let th s = X.th [X.pcdata s] in let td s = X.td [X.pcdata s] in let my_thead = X.thead (X.tr (th "") [th "X"; th "Y"; th "Z"]) [] in let my_tr1 = X.tr (td "1") [td "AAA"; td "BBB"; td "CCC"] in let my_tr2 = X.tr (td "2") [td "DDD"; td "EEE"; td "FFF"] in let my_tr3 = X.tr (td "3") [td "GGG"; td "HHH"; td "III"] in let my_tbody = X.tbody my_tr1 [my_tr2; my_tr3] in let my_table = X.tablex ~thead:my_thead ~a:[br] my_tbody [] in (my_table)</lang>
Oz
As a complete web application, using the "Roads" web programming library. Connect your browser to http://localhost:8080/table after starting the program. <lang oz>declare
[Roads] = {Module.link ['x-ozlib://wmeyer/roads/Roads.ozf']}
fun {Table Session}
html(
head(title("Show a table with row and column headings")
style(type:"text/css" css(td 'text-align':center) ))
body(
{TagFromList table tr(th th("X") th("Y") th("Z")) | {CreateRows 3 5} })) end
fun {CreateRows NumCols NumRows}
{List.map {List.number 1 NumRows 1}
fun {$ Row}
{TagFromList tr
td( {Int.toString Row} ) | {List.map {List.number 1 NumCols 1} fun {$ Col} SequentialNumber = (Row-1)*NumCols + Col in td( {Int.toString SequentialNumber} ) end }}
end }
end

{Roads.registerFunction table Table} {Roads.run}</lang>
PARI/GP
<lang parigp>html(n=3)={
print("

| X | Y | Z | |
|---|---|---|---|

Note also the built-in printtex command, which allows the analogous task to be written as
<lang parigp>printtex(matrix(4,4,i,j,if(i==1,if(j==1,"",Strchr(86+j)),if(j==1,i,random(9999)))))</lang>
Pascal
See Delphi
Perl
<lang Perl>my @heading = qw(X Y Z); my $rows = 5;
print '
<thead>" } @heading),"</thead><tbody>";
for (1 .. $rows) {
print "", (map { "" } @heading), ""; } print "</tbody>| ', (map { " | $_ |
|---|---|
| $_ | ".int(rand(10000))." |
";</lang>
Note that this is a rather inane way (because of the inane task specification) of generating structured document. For serious work, one should use a module such as XML or HTML for well-formedness instead of this ad hoc method.
Perl 6
This is certainly not the only or best way to generate HTML tables using Perl 6; just an example of one possible method.
<lang Perl6>my @header = < X Y Z>; my $rows = 5;
sub tag ($tag, $string, $param?) { return "<$tag" ~ ($param ?? " $param" !! ) ~ ">$string" ~ "</$tag>" };
my $table = tag('tr', ( tag('th', $_) for @header));
for 1 .. $rows -> $row {
$table ~= tag('tr', ( tag('td', $row, 'align="right"')
~ (tag('td', (^10000).pick, 'align="right"') for 1..^@header)));
}
say tag('table', $table, 'cellspacing=4 style="text-align:right; border: 1px solid;"');</lang>

Ruby
Pure Ruby solution:
<lang ruby> def r
rand(10000)
end
STDOUT << "".tap do |html|
html << "
" [ ['X', 'Y', 'Z'], [r ,r ,r], [r ,r ,r], [r ,r ,r], [r ,r ,r] ].each_with_index do |row, index| html << "" html << "" html << row.map { |e| ""}.join html << "" end html << "| #{index > 0 ? index : nil } | #{e} |
"
end </lang>
This creates a plain HTML table, without any CSS to draw borders or to set column widths.
<lang ruby>def r; rand(10000); end table = [["", "X", "Y", "Z"],
[ 1, r, r, r],
[ 2, r, r, r],

row.each do |cell|
xcell = REXML::Element.new("td", xrow)

Scala
Scala has built-in support for XML, so you can freely mix XML literals into your Scala source code. This is nice, because instead of using strings to represent XML, you create XML literals that the compiler can understand and verify. This approach lets you easily generate dynamic XML by interweaving Scala code and XML in the same expressions.<lang scala>object TableGenerator extends App {
val data = List(List("X", "Y", "Z"), List(11, 12, 13), List(12, 22, 23), List(13, 32, 33))
def generateTable(data: List[List[Any]]) = {
{data.zipWithIndex.map { case (row, rownum) => (if (rownum == 0) Nil else rownum) +: row}.
map(row =>
{row.map(cell =>
)}
)}

XSLT

<xsl:template match="/numbers"><xsl:apply-templates select="number[position() mod $column-count = 1]"/>
